{String | Object} p Optional: Predicate. A URI, prefixed name, or Symbol.
{String | Object} o Optional: Object. A URI, prefixed name, Symbol, or Literal.
{String | Object} w Optional: Data Source. A URI, prefixed name, or Symbol.
{Object} opts Optional: @see CommonOptions

Returns:: {Object} A Symbol, Literal, or BlankNode representing a match for the missing term, or undefined if none was found.
